Answer:
Please see below
Explanation:
Adapting to the surrounding environment is a critical part of surviving and, eventually, evolution. Take mice as an instance. Their coat color plays a major role in allowing to go undetected from potential predators if they are able to blend in well with the surrounding environment. Mice with a coat color that makes them stand out will be easily preyed on. Hence, those who have <u><em>adapted</em></u> to their environmental conditions will live to pass on their genes. This phenomenon is known as selection pressure.
Answer: Sea walnuts are marine invertebrates. They belong to the genus Mnemiopsis.
Explanation:
These animals have stinging tentacles like jelly fish and they often cast up or come to the sea shores where if they come in contact with humans can harm them by stinging.
The barrier if kept along the side of the sea shore and not allowing humans to reach to the shore can help in preventing the harm from these animals. The introduction of the predatory animals in the sea can also help in reducing their population.
The three benefits for removing the sea walnut:
1. The population of other species will increase as sea walnut is an invasive species.
2. The balance of the marine ecosystem can be maintained.
3. Humans can be protected from the harm caused by these animals.
Phloem is the food conducting tissue that has a two-way flow.
Explanation:
Plants prepare food on their own and plants also have conductive cells that carry out transportation process. Plants are divided into two types based on their conductive system i.) vascular plants ii.) non vascular plants.
Vascular plants are those plants which have special conductive cells called phloem and xylem.
Xylem transports water from roots of the plants to other parts of plants and also provides mechanical support to plant. It is uni-directional.
Phloem is the food conducting tissue that transports food to plant and also have bi-directional movement.
certain hydrogen bonds are formed so that A goes with T and G with C
Answer:
Explanation:
A gray squirrel can either have the same alllele GG or have two different allele Gg this will determine the percentage of the offspring that will be Grey.
For 2 parent with same allele
GG × GG
!
GG GG GG GG
all are grey 100%
For 2 parents with different allele
Gg × Gg
!
GG Gg Gg gg
75% will be grey
25% other color
